Feature Req: Close comments on all posts

I often finding myself cleaning up other people’s WordPress messes, which includes adding AIOWPS, of course. It also involves locking down commenting (holding comments for moderation, etc.), and running a little SQL:
UPDATE XX_posts set comment_status='closed';
to make sure there aren’t old pages that have been left with comments open.

THE SUGGESTION:
It would be good to have a single “Lock down comments” option in AIOWPS that did all this. If enabled, perhaps the dashboard could include an alert if someone creates a post with commenting enabled. (I do this for pings as well, so perhaps that could be part of it too.)

Thanks,
Colin
